In their own words
Screaming Frog SEO Spider
Screaming Frog SEO Spider crawls websites to audit more than 300 SEO issues and support improvements to search performance and user experience. It finds broken links and server errors, checks redirects, and flags page titles and meta descriptions that are missing, duplicated, or too long. For JavaScript-heavy sites, it can render pages with its integrated Chromium WRS, including sites using Angular, React, and Vue.js. Data extraction supports CSS Path, XPath, regular expressions, and custom JavaScript. The crawler connects to Google Analytics, Search Console, and PageSpeed Insights APIs, with link-metrics integrations for Majestic, Ahrefs, and Moz. Crawls can be scheduled, automated from the command line, exported to destinations such as Google Sheets, and compared across runs or between staging and production. The free version costs nothing and allows 500 URLs per crawl; saving crawls, configuration, and advanced features are restricted. The paid version costs $279 a year per licence, with unlimited crawl size subject to allocated memory and storage. It runs on Linux, macOS, and Windows.
